qemu.bbclass: Allow use different QEMU binary depending of target

There are architectures which support running in 32 and 64 bit
flavours however the simulation is provided in a specific QEMU
setting, requiring us to use a different binary. This patch allow this
to be done using, for example:

QEMU_TARGET_BINARY_ppce5500 = "qemu-ppc64abi32"
